ROV05-201K-S-2

Voltage-dependent or transient voltage suppressors (TVSs) including varistors (VDRs), metal-oxide varistors (MOVs), and silicon avalanche diodes (SADs) are major components in electronics industry for various applications such as transient voltage protection, surge protection, peak current protection, and voltage switching.

ROV05-201K-S-2 is an MOV designed for protecting circuits from the damaging effects of over-voltage transients. It works by limiting the transient voltage by the clamping voltage so that voltage rise is clamped.

The working of ROV05-201K-S-2 can be divided into two stages: a non-linear stage, and a linear stage. In the non-linear stage, when a high voltage transient appears, the MOV is triggered and the high voltage is clamped. The clamping voltage is the breakdown voltage of the MOV, which is normally 20% to 30% higher than the nominal value. The clamping voltage of ROV05-201K-S-2 is 201V and its maximum voltage rating is 315V. In the linear stage, the MOV follows the linear resistance until the current reaches the saturation current of the MOV. Then, the MOV limits the current flow and absorbs the excessive energy produced by the transient. The saturation current of the ROV05-201K-S-2 MOV is 5.2 Amps.

ROV05-201K-S-2 can be used in various applications including power supplies, batteries, connectors, surge protectors, AC/DC converters, laser diodes, motor control, and automotive electronics. It is also suitable for industrial, medical, and many other applications. For example, it can be used as a power switching device in electronic systems, switching from AC to DC or vice versa. It can also be used as a surge protector in power lines, preventing ac transients. In addition, it can be used in automotive systems to protect against spikes and surges. Moreover, it can be used in laser diodes to limit the current and protect the device from damaging voltage transients.

In conclusion, ROV05-201K-S-2 is an MOV designed for providing protection for electronic components against sudden voltage changes. With its high withstand voltage, saturation current, and fast responding time, ROV05-201K-S-2 is suitable for many applications in various industries, including power supplies, batteries, connectors, surge protectors, AC/DC converters, motor control, and automotive electronics.
